Ok, so I think I've decided on the 510. Before I order, I'd like to know what vendor you all have had the best luck with? Also, I thought I'd go ahead and get some e-liquid, but I'm not sure what strength to get. I usually smoke lights, but they're Camel, so they might be a little stronger than a Marlboro Light. Lasly, any handy-dandy coupon codes??
